Programmable Registers
5.4.1 Interrupt Collector Interrupt Vector Address Register
This register is read by the Interrupt Service Routine using a load PC instruction. The priority
logic presents the vector address of the next IRQ interrupt to be processed by the CPU. The
vector address is held until a new ISR is entered..
HW_ICOLL_VECTOR: 0x000
HW_ICOLL_VECTOR_SET: 0x004
HW_ICOLL_VECTOR_CLR: 0x008
HW_ICOLL_VECTOR_TOG: 0x00C
This register mediates the vectored interrupt collectors interface with the CPU when it enters
the IRQ exception trap. The exception trap should have a LDPC instruction from this address.
